In the production process of some industries, the product needs to be wound on the drum, a problem that needs to be solved here is how to make its diameter from the beginning to the gradual increase of the whole process, keep the change of tension and linear speed within the allowable range? YLJ series torque motors have such electrical characteristics.

Shengzhou Senli Electric Motor organized the first dose of COVID-19 vaccine for its employees in batches on May 8, 2021 and May 13, 2021; A team appointment model was adopted, and all employees were actively vaccinated against COVID-19 despite no contraindications. -- I am the first to vaccinate the entire population.

The motor is mainly composed of magnetic conductive material - silicon steel sheet, coil winding - copper wire and frame shell. The working principle is the law of electromagnetic induction, and the motor is to convert electrical energy into mechanical energy. The following and Senli motor Xiaobian together to discuss the requirements for the purchase of three-phase asynchronous motors.

Torque motor can be divided into winding type and roll type. When winding type is blocked, the moment is the peak moment and the current is the peak current. Because the torque almost does not change (or is very small) when the speed changes, the torque is still its rated torque when it is blocked.

As a torque motor manufacturer with 19 years of research and development and production experience, what is the shipping process of Senli electric? Today, Senli Motor Xiaobian will take you into our delivery site to find out.

When we use three-phase asynchronous motors, if the load of the drag exceeds the rated capacity, the motor will be overloaded, and some abnormal phenomena will occur. How to judge overload? What kind of phenomena will be produced? Shengzhou Senli motor with you to discuss the next.

Three-phase asynchronous motor is a kind of equipment that converts electrical energy into mechanical energy. When the stator winding passes through the three-phase current, the rotating magnetic field will be generated in the rotor winding, the induced electromotive force will be generated in the rotor winding of the closed loop, the rotor current and the magnetic field will interact to produce electromagnetic torque, so that the rotor drives the mechanical load to rotate.

Torque motor has the characteristics of large torque, low speed, is according to the production requirements of an asynchronous motor; Because in some cases, it is required to be able to maintain a period of time or run in a long-term state of blocked rotation. The more common question asked about this motor is: Why does the motor not burn out when it is blocked for such a long time?

The purpose of no-load test is to check the assembly quality and operation of three-phase asynchronous motor, and to measure the no-load current and no-load loss power of motor. The motor gradually increases the voltage to the rated value (380V), at which time the motor should operate stably without abnormal noise and vibration. The value measured by the ammeter is the no-load current, and the input power value displayed by the power meter is the no-load loss power of the motor. The no-load current should be balanced in three phases, and the average deviation between any phase no-load current and three-phase current should not be greater than 10%. The percentage of no-load current and rated current should conform to the values listed in the following table

In the production process of some textile, paper, metal processing, plastics and other industries, it is often necessary to wind the product on the drum or reel operation, here a problem that needs to be solved: how to keep the change of tension and line speed within the allowed range during the process of gradually increasing the drum diameter from the beginning to the back. Torque motor can just perfectly solve this kind of problem, which is one of its characteristics.
